SPECIFICATION foning part f Letters Patent No. 696,514, dated April. 1, 1902.

Applcation filed J'unc 26, 1.901.

To @ZZ whom, t may concern:

Be it known that I, HERBERT M. STURGIS, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Heating Apparatus, (Case No. 3,) of which the following is a full, clear,concise,and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to devices for heating curling-irons, and has for its object the provision of a structure of this class that may be 'quickly and effectively united with or placed upon a gas-jet and which is also adapted for quick removal from the gas-jet.

In practicing myinvention I employa union adapted for quick engagement with and separation from the gas-jet, which union is pret'- erably brazed or otherwise integrally secured to a duct formed, preferably, in the shape of Y a gooseneck, which duct projects tor a suitable distance parallel to the union and is bent at right angles thereto a sufficient distance below the union to clear the globe and globeholder and other parts of the gas-fixture, whereby existing gas-fixtures need not be modified nor globes that may be in place re- 'moved in order to effect the placement of the heater. The lower angularly-extending portion of the duct is provided with a series of apertures through which gas passed from the gas-j et through the union and duct mayissue. These apertures are arranged to produce flames, lying in a plane coincident with the vertical diameter of the said angular extension to strike the bottom of a receiving-tube located above the apertures. This receivingtube is provided with end plates, which are preferably rigidly secured thereto. The angular extension engages the lower portions of these end plates, loosely passing through a hole provided in one end plate and being se- .cured .to the other end plate by means of a machine-screw passing through a corresponding hole and having threaded engagement with the interior of the duct to thereby prevent the escape of gas at vthe other end of the duct, as Well as to engage the same with the 5o said end plate. A bracing means is interposed between one of the end plates and the Serial No. 66,051. (No model.)

vertical portion or" the duct toprevent the ver-u tical and horizontal branches of the duct from being displaced or sagging.

I have thus specifically outlined the preerred embodiment of the invention; but I do not wish to be limited to this species of the invention in all the claims.

I will explain my invention more fully by reference to the accompanying drawings,illus- 6o trating the preferred embodiment thereof, "in which- Figure lis a side elevation of a curling-iron heater embodying the invention, the same being united with an ordinary gas-jet. Fig. 2 65 is a sectional elevation of the heating apparatus illustrated in Fig. l. Fig. 3 is a plan view showing the bracing means. Fig. tis a sectional view on line 4 4L of Fig. l. Fig. is a top view ofthe gas-duct, showing the per- 7o forations therein.

Like parts are indicated by similar characters of reference throughout the different iigures.

In Fig. l I have illustrated one of the many types of gas-jets to which and from which my device may be readily attached and detached. In this instance the gas-jet o, is provided upon the end of a gas-pipe b :in the form of a wall-bracket having a controlling- 8o cock c, located near the wall. The location of the valve or cock c is immaterial, as the device of my invention is adapted for use in connection with all forms ot gas-fixtures now upon the market.

I employ a duct d, made ot' thin metal. This duct is provided with a semicircular curved portion e, that is preferably rigidly united with a union f by being brazed thereto. This union is adapted for unthreaded engagement 9o with the gas-tip, and I use the term unthreaded union occurring in the claims in this sense, as it is obvious the union might be provided with threads for other purpose. This union is provided with a cap g, having a cylindrical extension h, around which is placed a section of rubber tube t', which is clamped between the extension and the outer wall of the union, whereby the rubber tube may be readily placed in engagement with Ioo the selected gas-tip and readily removed from engagement with the gas-tip, while at the same time a gas-tight fit is provided for conveying the gas from the pipe b through the duct d. 'Ihis duct has a horizontal extension k, which is joined with the semicircular portion or offset portion c by the vertical or upright stretch of the duct. The horizontal extension k is provided with a series of apertures Z, constituting jet-openings. I prefer to employ these distinct jet-openings rather than an elongated slot; but I do not wish to be limited to the jet-openings, which, in fact, I herein consider as the equivalent of a continuous slot, and the claims are drawn with this equivalency in View; nor do I wish to be limited to the placement of the jet-openings in a single straight line.

The receiving-tube m, within which the "tongs of the curling-iron n may be inserted,

is rigidly secured at its ends to the end plates 0 and p, this tube constituting the preferred form of curling-iron support. The end plate o is provided with an aperture through which the duct portion 7c freely slips, while the end plate p is provided with an aperture through which a fastening-screw qrmay pass into engagement with threads provided within the bore of the duct portion 7c, the screw q being preferably in the form of a machine-screw whose head is of a considerably larger diameter than the diameter of the duct, whereby the end plate p is held between the head and the end of the duct to not only secure the heating-tube m in proper relation to the duct portion 7c, but also to seal the end of the said duct portion to prevent the escape of gas. To secure effective combustion of the gas passing through the duct, I provide an aperture r, affording direct communication between the surrounding atmosphere and the bore of the duct. By locating this aperture, which is preferably in the form of a wide slot, in the bottom of the duct the escape of gas therethrough is prevented, while the air is readily drawn within the duct or tube during the combustion of the gas to effect a thorough intermixture of the gas and air to produce a most effective combustion. As this cut or slot fr is likely to weaken the tube, which is preferably of a uniform diameter throughout, I provide a bracing device, which properly strengthens the tube to prevent the weight of the curling-iron from bending the tube at the said slot. For this purpose a hook s, that is rigidly secured to and preferably stamped out of the same metal with the end plate 0, is provided. The receiving-recess of this hook engages the vertical length or stretch of the gas-duct d to thereby preserve the proper angular relation between the vertical and horizontal lengths of the said duct, so that the presence of the slot r, which is preferably located in t-he horizontal portion 7c, does not detract from the rigidity of the structure. The heating-tube 'm coacts with the duct portion 7c to hold the curlingiron in position; otherwise the curling-iron, although gripping a platenvould of its own weight tend to rotate to a vertical position. By interposing thecurling-iron between the duct m and the duct portion lo the curlingiron is placed at a convenient angle to be readily accessible to the user.

It will be observed that I have provided a union with a smooth or unthreaded bore, whereby the union may be readily placed in engagement with a gas-tip by a mere vertical motion and removed from this engagement also by a mere vertical motion. Thus the curling-iron heater need not be permanently associated with any given gas-jet, nor need any gas-jet be especially readj usted or modiied to suit the heater.

I-Ieretofore curling-iron heaters in commercial use have been provided-with. threaded unions adapted for thread ed engagement with specially-provided gas-jet fittings, which necessitated a perfect and complete engagement between t-he unions and the special fittings, so that the position of the curling-iron heater with reference to the wall could not be readily adjusted. By means of my invention the curling-iron heater may be placed in any position and have its position readily readjusted without causing a leakage of the gas.

While lI have herein shown and particularly described the preferred embodiment of my invention, itis obvious that changes may be made Without departing from the spirit thereof, and I do not, therefore, wish to be limited to the precise construction shown; but,

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a heater, the combination with a gasduct provided at one end with an unthreaded union adapted to be slipped over a gas-jet, the said duct being provided with an offset portion c, a vertical or upright stretch and a stretch angularly disposed with respect to the vertical or upright stretch, the angular stretch being provided with a plurality of jetopenings arranged longitudinally thereof, of a curling-iron support adapted to secure the curling-iron in a longitudinal position with respect to the angular stretch of the gas-duct, and means for bracing the upright and angular stretches of the gas-duct to prevent their displacement by the supported curlingiron, substantially as described.

2. In a heater, the combination with a gasduct provided at one end with an unthreaded union adapted to be slipped over a gas-jet, the said duct being provided with an offset portion e, a vertical or upright stretch and a ,stretch angularly disposed with respect to the vertical or upright stretch, the angular.

stretch bein g provided with a plurality of jetopenings arranged longitudinally thereof, of a heating-tube spaced apart from said duct for receiving the tongs of a curling-iron located above said jet-openings, end plates uniting the angular stretch of the gas-duct with the heating-tube, the said end plates be- IOO IIO

ing separated, whereby the tongs of the heating-iron may engage an end plate and through the means of the said heating-tubeand the angular stretch of the gas-duct be prevented from rotating or becoming disengaged from the engaging end plate, and bracing means forpreventing relative displacement between the vertical and horizontal stretches of the gas-duct, substantially as described.

3. The combination with a gas-duct provided with upright and angular stretches, the angular stretch being provided with longitudinally-arranged jet-openings, of a heatingtube spaced apart from said duct, and end plates uniting the heating-tube with the angular stretch of the gas-duct, the said plates having free opening between them, whereby the curling-iron may be inserted between the duct and tube to grasp an end plate and to secure the iron in an angular position, substantially as described.

4. The combination with a tube for receiV- ing the tongs of a curling-iron, of a gas-duct spaced apartfrom said tube for directing a gas-Haine against the said tube, and a plate p uniting the tube and gas-duct the space between the duct and tube being free, whereby the curling-iron may be inserted between the duct and tube to grasp the plate and secure the iron in an angular position, substantially as described.
